Mathematical Model with Feedback Loop in Company Control

This article is devoted to the further development of feedback loop models. They are used in management a single-industry firm. The studying consists mathematical modeling transients and assessing their impact on economic indicators. To solve this problem, following was done article. A structural model functioning firm (SIF) presented. It built accordance with theory automatic control (TAC) includes elements: unit, production sales information nodes, as well (FL). Equations relationships describing logic company system allowed us derive dynamic differential equations that reflect loops revenue costs. expressions operator form presented, which describes contour FL SIF. has equations. forms basis SIF system. made it possible obtain graphical interpretation closed open based use Mathcad editor. Transients fluctuations volumes costs presence disturbing influences. scientific result determines novelty
